wish I'd discovered these years ago

These are terrific. They do the key job of preventing chafing, but more than that, they're lightweight and comfortable to wear - and I mean comfortable to the point of forget-you're-wearing-them.

What I hoped for

I bought 2 pair of Undersummers. I loved them so much I ordered more, in different colors. They are wonderful in preventing thigh chafing, especially here in Florida.

Love the Slipshort!

Wore these today under some slinky knit fabric pants. Kept me cool and help keep the pants for being too clingy. Undersummers are the only brand where I spend this kind of money on "underwear" (they are truly more than just underwear.

Not sure..

My first order, I used the size chart, and it was too large. I exchanged for a smaller size. The fit still isn’t right. I put the shirts on and wore them around the house while I was getting ready for my day. The shorts ride up and rub my legs more than when I don’t have them on, which kind of defeats the purpose of the shorts. I’m not sure if the size is still not right or what. I’m not sure I can return them, since I “wore” them, even though they still have the tags attached. I’m just not sure!

Poor quality. Terrible service.

Quality was not as expected. Repeated attempts to reach out to customer service and no response. Voicemail is full. No response to emails. Steer clear.

Beating the New Jersey Humidity

These were so comfortable and made wearing a sundress in the WORST Jersey humidity no issue. Usually a dress in the summer months is impossible but with my undersummers I will change my summer clothing options to more sundresses! Thanks for a great product

My summer saviour!

The actual shorts themself are amaaaazing. Breathable, classy, comfy and they save my Thighs from the angst of chafing! The only thing I would be happy to see improvement on is delivery with a courier to Canada where you pay minimal import fees upfront (like DHL) rather than an obscene amount of COD when they arrive.

Thanks for giving me dresses/skirts back!

Love them! I feel like I can comfortably wear skirts and dresses again. They do not ride upon the legs at all. I will definitely buy more!

Better than I expected

Bought 2 of these and they are so so light and super comfortable, I wear them by themselves at home now because of how comfy they are. I was a bit worried about the pricepoint but they are so worth it, love them!

Shortlettes are generously sized  to hug but not squeeze your curves.  They are not compression and do not feel like nylons/hosiery, shapewear, bike shorts, or compression pants.  Shortlettes are simply comfortable.  They are not made to be tight, feel constricting, shape, pinch, or bind.  The longer lengths allows for maximum chafe protection and comfort.

Correct Fit Guidelines:
✔️ Waist should not roll
✔️ Body should glide comfortably against the skin
✔️ Legs should not ride up while walking

Signs of Incorrect Fit:
✖️ Baggy crotch (too big)
✖️ Running at the seams/Wears to fast (too small)
✖️ Slides Down (too small)
✖️ Legs ride up (too small)

Which is the best fit?

CarrieRae's Recommendations:

Under 5'4" - High Thigh, Athletic, or Classic Styles

Plus Size - Fusion, Classic, or Original Lace

Apple Shaped - Fusion, Classic, or Original Lace

* Order the size in-between your waist and hip measurement.  I.e.  Waist 3X + Hip XL = Order 2X

Pear Shaped - Try them all!

Hourglass - Lace or High Thigh

Slender - High Thigh or Athletic

My Shortlettes fall down, why? Are Shortlettes shape wear? Are they compression shorts?
How are Shortlettes different than other slip shorts or bike shorts? How long do Undersummers products last? Can you let your Shortlettes Show?
